Rational Emotive Behavior Therapy (REBT)
A comprehensive guide to REBT: how Albert Ellis's pioneering approach identifies and disputes irrational beliefs to reduce emotional suffering.
What Is Rational Emotive Behavior Therapy?
Rational Emotive Behavior Therapy (REBT) is a form of cognitive behavioral psychotherapy created by psychologist Albert Ellis in 1955. It is widely considered the first cognitive behavioral therapy — predating Aaron Beck's Cognitive Therapy by about a decade — and it laid the groundwork for the entire CBT family of therapies.
REBT is built on a core philosophical insight: it is not events that disturb us, but our beliefs about those events. This idea, which Ellis drew from the ancient Stoic philosophers Epictetus and Marcus Aurelius, became the foundation of a practical and often direct therapeutic approach that helps people identify, challenge, and replace the irrational beliefs that cause emotional suffering.
While REBT shares much in common with CBT, it has a distinctive philosophical emphasis on unconditional self-acceptance, high frustration tolerance, and the disputation of absolutist thinking. REBT also tends to be more direct and confrontational in style than standard CBT, though modern practitioners adapt the approach to suit each client.
How It Works
The ABC(DE) Model
REBT's core framework is the ABC model, extended to include D and E:
- A — Activating Event: Something happens (you get criticized at work)
- B — Belief: You interpret the event through a belief ("I must always perform perfectly; this proves I am worthless")
- C — Consequence: Emotional and behavioral consequences follow from the belief (depression, withdrawal)
- D — Disputation: The therapist helps you challenge the irrational belief ("Where is the evidence that one criticism makes you worthless? Must you always be perfect?")
- E — Effective New Belief: You develop a more rational, flexible belief ("I prefer to do well, but imperfection does not make me worthless")
Core Irrational Beliefs
Ellis identified several categories of irrational beliefs that underlie most emotional disturbance:
- Demandingness: Rigid "musts" and "shoulds" ("I must succeed," "Others must treat me fairly," "Life must be comfortable")
- Awfulizing: Catastrophizing ("It is awful and terrible when things do not go my way")
- Low Frustration Tolerance: Believing you cannot stand discomfort ("I can't bear this")
- Global Rating: Rating your entire self or others based on single attributes ("I am worthless because I failed")
Techniques
REBT employs cognitive, emotive, and behavioral techniques:
- Cognitive: Socratic questioning, logical analysis, identifying and disputing irrational beliefs
- Emotive: Shame-attacking exercises, rational-emotive imagery, forceful self-statements
- Behavioral: Graded exposure, behavioral experiments, skill rehearsal

What to Expect
REBT sessions are active and collaborative, but often more direct than other therapies. Your therapist may challenge your beliefs firmly and use humor to help you see the absurdity of irrational demands. This is not done harshly — it is done with warmth and the goal of helping you think more flexibly.
A typical session involves identifying a recent situation that triggered distress, mapping it onto the ABC model, disputing the irrational beliefs involved, and developing more rational alternatives. You will likely have homework assignments between sessions — practicing disputation, completing REBT worksheets, or doing behavioral experiments.
REBT can be delivered in individual or group format and typically involves 12 to 20 sessions, though the length varies depending on the complexity of the issues.
Conditions It Treats
REBT has been applied to a wide range of conditions:
- Anxiety disorders — including social anxiety, generalized anxiety, and phobias
- Depression
- Anger and hostility
- Procrastination and low frustration tolerance
- Relationship difficulties
- Performance anxiety (sports, academic, professional)
- Stress management
Effectiveness
REBT has a substantial evidence base, though the research literature is smaller than that for CBT as a whole. Meta-analyses, including a 2017 meta-analysis by David, Cotet, Matu, Mogoase, and Stefan published in the Journal of Clinical Psychology, found that REBT produces significant effects for anxiety, depression, and overall distress, with effect sizes comparable to other CBT approaches.
Compared to standard CBT, REBT places more emphasis on philosophical change and unconditional self-acceptance, and tends to be more direct in style. CBT may focus more on specific automatic thoughts, while REBT targets the deeper irrational beliefs underlying them. Compared to ACT, REBT actively disputes irrational beliefs, while ACT teaches acceptance and defusion from difficult thoughts without directly challenging their content. Both share an emphasis on reducing the impact of unhelpful cognitions on behavior.
REBT is actually the original cognitive behavioral therapy — it predates CBT by about a decade. The main differences are that REBT has a stronger philosophical foundation (emphasizing unconditional self-acceptance and rational living), tends to be more direct in style, and focuses on deep-level irrational beliefs rather than surface-level automatic thoughts. In practice, there is considerable overlap between the two.
REBT can be more direct than some other therapies — your therapist may firmly challenge irrational beliefs and even use humor. However, this is always done with warmth, respect, and therapeutic purpose. Modern REBT practitioners adapt their style to each client, and the approach is collaborative, not aggressive.
It means accepting yourself as a complex, fallible human being without rating your entire worth based on individual actions or traits. You can acknowledge that a behavior was unhelpful without concluding that you are a worthless person. This is distinct from self-esteem, which REBT views as conditional and fragile.
Yes. REBT has a strong track record with anger, which Ellis saw as frequently stemming from irrational demands that others 'must' behave a certain way. REBT helps you shift from rigid demands to flexible preferences, reducing the intensity of anger while still allowing you to assert your needs appropriately.
